Ti Tree Gas to Energy Project

Ti Tree Gas to Energy Project is a landfill gas project located at the Ti Tree Bioenergy Facility in Willowbank, approximately 15km southwest of Ipswich in Queensland. It was registered in November 2012. The facility is uniquely situated in a 36-million cubic metre void left over from a previous open-cut coal mining operation.

Landfill gas methodology projects involve installing a gas collection system to capture environmentally damaging methane that is generated by decomposing organic waste. The captured biogas is then combusted, either by flaring or by feeding it into generators to produce renewable electricity, preventing the methane from entering the atmosphere and significantly reducing greenhouse gas emissions.

The Willowbank and broader Ipswich area typically experiences a sub-tropical climate characterised by moderate to high rainfall. Regional soils are generally made up of clay and alluvial deposits, though the exact project site has been heavily modified by its industrial history. Surrounding land use is a diverse mix of industrial operations, peri-urban development, and agricultural grazing.

This project transitioned from a revoked Carbon Farming Initiative (CFI) method and continues to capture gas generated from both legacy and non-legacy waste. The Ti Tree Bioenergy Facility operates as a joint venture between Veolia Environmental Services and JJ's Waste & Recycling. It produces enough green electricity to power approximately 2,500 homes annually. Additionally, the project delivered on a Carbon Abatement Contract (CAC254087) with the Australian Government, which was successfully completed in August 2022.
